Quick Sync is only good for en/decoding MPEG2/4 based codecs. It does not help with delivery codecs like Pro Res, HDCAM/R or DNxHD etc. If your output is only H.264, MPEG2 (HDV, XDCAM HD), MPEG 4(AVCHD, AVC I etc), then using Quick Sync can improve output up to 30% faster, depending on what kind of effects are used. This is tests on Adobe CS5.5 using the Intel Quick Sync SDK. Basically, the more effects tossed in like color correction, MBS etc, the less difference there. I'm not sure if it's because of the developmental software not being optimized for the various plug-ins etc.
Wags, even an 4 core i7 Bloomfield will run 4 layers of H.264 .mov full res real time in a sequence on CS6, with color correction even, with a CUDA card. No sweat on a 12 core. The Edius 6.5 (beta copy) can't do .r3d with source setting, which is an important element in dealing with .r3d files. CS6 can.
Jon, since you are dealing in 4k now, if you have a 12 core or even 8 core XEON, perhaps you should think about looking for a Nvidia Quadro 4000 card instead. It still won't let you do .r3d in realtime (you'll need a Red Rocket for that!) but if you deal with 2k conversions, it works well. Without a Red Rocket, you'll get pretty decent playblack but not realtime. If you are thinking of switching to Windoze, you will definitely need to stick with Nvidia CUDA since CS6 doesn't allow the use of OpenCL Gpu acceleration in Windoze.
As for Speed Grade, still needs to be rendered out from PP to SG, but not back. One can load directly into SG but will have to be rendered out back to PP. That's a pain. The UI is pretty simple but I feel the power of Resolve is so much better plus it's FREE!!! It is slower on the encode though.
Edit: Just tried 5 layers of H.264 from ALL-I off the MBP using CS6 OpenCL acceleration.
